JOHN RAPHAEL ROGERS, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTI-IALERLINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

Application filed July 19, 1911, Serial No. 639,340.

To all whom it may concern:

Be it known that 1, JOHN RAPHAEL Roo- ERS, a citizen of the UnitedStates, residing at Brooklyn, county of Kings, and State of New York,have invented a new and useful Improvement in Typographical Machines, ofwhich the following is a specification.

My invention relates to typographical ma-- chines, and more particularlyto those of the class now known to the public under the vname linotype,as represented, for instance, in U. S. Letters Patent No. 436,532. insuch machines the linotype or slug is formed in a mold connected to arotatably mounted disk or wheel, whereby the mold is presented first inposition to cooperate with a line of matrices in casting the slug, andis thereafter carried past a stationary knife to trim the base of theslug, and is finally arrested in front of an ejector blade by which itis forced from the mold. This disk or mold wheel is mounted on asupporting slide, whereby the mold is carried forward toward the line ofmatrices preparatory to the casting operation and is thereafterretracted to separate the edge of the slug from thematrices and to ermitthe rotation of the mold wheel. Di culty has been experienced in thetrimming of large or heavy slugs which ofier great resistance to theknife, because of the tendency of the wheel to spring forward away fromthe knife, which should remain in close contact with the rear face ofthe mold throughout the trimming action. This tendency if not correctedresults in the slugs being left with either excessive or unequal heightbetween their ends. To correct this difiiculty and to give more rigidsupport to the mold, machines have been constructed with a support orbearing arranged to act against the front face of the mold wheel andopposite the cutting edge of the knife on the rear side, whereby thewheel is supported in direct opposition to the knife, which thereforeremains in close contact with the base of the mold from oneend to theother. Such an arrangement is shown, for instance, in the ll. S. LettersPatent to G. A. Bates, No. 722,354, March 10, 1903. One objection to theconstruction therein illustrated is that the rest or support F passesover and around the edge of the mold wheel and to the opposite facethereof, and therefore its loca-- tion is inconvenient and prevents theappli- Specification of Letters Patent.

cation to the mold wheel of various improvements and additions whichhave been devised in the more refined and rapidly growing art. In orderto secure the same advantages and results, as previously set forth, andalso to leave the front face of the mold free and clear fromobstruction, I provide the mold support with clamping devices whlchengage a groove in the mold wheel, instead of passing around and beyondit as heretofore. In the particular form illustrated in the accompanyingdrawing, the clamping device comprises an extended finger so shaped andlocated as to engage such a groove in the edge or periphery of thewheel. However, other forms and variations will suggest themselves tothose skilled in the art, and still be comprised within the scope of myinvention; and, generally speaking, I desire it to be understood thatthe invention is not limited to any specific form or embodiment exceptin so far as such limitations are specified in the claims.

Referring to the drawing: Figure 1 is a perspective detail view ofportions of the mold wheel and mold slide, and the clamping devices onthe silde to engage the wheel; Fig. 2 is a rear elevation of portions ofthe mold wheel and mold slide, and also of the trimming knife andclamping devices; and Fig. 3 is a sectional detail taken substantiallyon the line 3-3 in Fig. 1.

Referring to the drawing, the mold wheel A is rotatably mounted on themold slide B, and the knife E, which trims the base of the slugs orlinotypes, is also connected to the slide B, all in the usual manner.The mold wheel A is, however, formed in its periphery with a groove C,between the ends of the teeth thereon and so as to leave teeth onopposite sides of the groove and on the slide B are mounted one or moreclamping devices F, F, suitably shaped and positioned to engage in thegroove. It will be seen that by this arrangement the wheel A. will beheld in correct and rigid relation to the trimming knife E, and that theouter face of the mold wheel will be left clear and free and in suchcondition as to permit the application of other parts thereto.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is as follows:

1. In a linotype machine, the combination of a support, the toothed moldwheel rotatably mounted thereon the said teeth being cut away betweentheir ends to provide a circumferential groove with teethv on 0ppositesides thereof, and fixed clamping means to engage in said groove andthus to hold the wheel in correct relation to its sup ort. 1 p 2 In alinotype machine, the combination of a mold slide and the toothedmold-wheel rotatably mountedthereon, the said teeth being cut awaybetween their ends to provide a circumferential groove with teeth onopposite sides thereof, and the slide being'provided with means tobridge the teeth on one 15 side of the. groove and to engage in saidhand this 18th day of July, 1911, in the pree 2o enoe of two attestingwitnesses.'
